   * The `Status` type defines a logical error model that is suitable for

   * used by [gRPC](https://github.com/grpc). The error model is designed to be:
   * - Simple to use and understand for most users - Flexible enough to meet
   * unexpected needs  # Overview  The `Status` message contains three pieces of
   * data: error code, error message, and error details. The error code should
   * be an enum value of google.rpc.Code, but it may accept additional error
   * codes if needed.  The error message should be a developer-facing English
   * message that helps developers *understand* and *resolve* the error. If a
   * localized user-facing error message is needed, put the localized message in
   * the error details or localize it in the client. The optional error details
   * may contain arbitrary information about the error. There is a predefined
   * set of error detail types in the package `google.rpc` that can be used for
   * common error conditions.  # Language mapping  The `Status` message is the
   * logical representation of the error model, but it is not necessarily the
   * actual wire format. When the `Status` message is exposed in different
   * client libraries and different wire protocols, it can be mapped
   * differently. For example, it will likely be mapped to some exceptions in
   * Java, but more likely mapped to some error codes in C.  # Other uses  The
   * error model and the `Status` message can be used in a variety of
   * environments, either with or without APIs, to provide a consistent
   * developer experience across different environments.  Example uses of this
   * error model include:  - Partial errors. If a service needs to return
   * partial errors to the client,     it may embed the `Status` in the normal
   * response to indicate the partial     errors.  - Workflow errors. A typical
   * workflow has multiple steps. Each step may     have a `Status` message for
   * error reporting.  - Batch operations. If a client uses batch request and
   * batch response, the     `Status` message should be used directly inside
   * batch response, one for     each error sub-response.  - Asynchronous
   * operations. If an API call embeds asynchronous operation     results in its
   * response, the status of those operations should be     represented directly
   * using the `Status` message.  - Logging. If some API errors are stored in
   * logs, the message `Status` could     be used directly after any stripping
   * needed for security/privacy reasons.
